Lymph nodes may become swollen or enlarged as result of invasion by cancer cells. Swollen lymph nodes may be palpated (felt) during a physical exam. Before lymph nodes are removed, a small amount of tissue is usually removed. A biopsy will be performed...
on it to check for the presence of abnormal cells.
The patient will be asked to stop taking aspirin or aspirin-containing drugs for a period of time prior to surgery, as these can interfere with the blood's ability to clot. Such drugs may include prescription blood thinners (for example, Coumadin—generically known as warfarin and heparin). However, patients should discuss their medications with regard to their upcoming surgery with their doctors, and not make any adjustments or prescription changes on their own. No food or drink after midnight the night before surgery will be allowed.

Other Information
Lymphadenectomy consists of the surgical removal of one or more groups of lymph nodes. It is almost always performed as part of the surgical management of cancer.
This is usually done because many types of cancer have a marked tendency to produce lymph node metastasis early on in their natural history. This is particularly true of melanoma, head and neck cancer, differentiated thyroid cancer, breast cancer, lung cancer, gastric cancer and colorectal cancer. Famed British surgeon Sir Berkeley Moynihan once remarked that "the surgery of cancer is not the surgery of organs; it is the surgery of the lymphatic system".
The better known examples of lymphadenectomy are axillary lymph node dissection for breast cancer; radical neck dissection for head and neck cancer and thyroid cancer; D2 lymphadenectomy for gastric cancer; and total mesorectal excision for rectal cancer.
